Vandle
I come from a connection manager

You already have the right idea. You deserve a client that keeps up with it.

mRemoteNG got there first: one tree, many protocols, inheritance down the branches. Vandle is that idea rebuilt on a native cross-platform shell, with routing and encrypted central state designed in rather than added on.

Credit where it is due

mRemoteNG is free, has held a tabbed multi-protocol workspace together for years, and its inheritance model is a genuinely elegant answer to repetitive connection config.

What changes

Four things you get that you did not have.

Side by side

mRemoteNG and Vandle

Aspect mRemoteNG Vandle
Platforms Windows Windows, Linux, macOS
Connection store A local XML file, optionally encrypted A central store you point at, live-synced, secrets encrypted
Routing Per-connection SSH tunnel or gateway A route object, assigned or inherited, switchable at runtime
File transfer External tools A built-in file surface with remote-to-remote transfer

Moving over

What it takes

Your tree translates directly: folders stay folders, and the route you were repeating on every child moves up one level.

And the rest of it

Four more protocols came along

Replacing one tool gets you five. Whatever else that machine speaks is already a row on the same record - and every one of them takes the route you assigned.

Web

Real browsing, properly routed

SSH

A terminal that keeps up

SFTP

Two remote panes, no detour

WebDAV

The other half of file transfer

RDP

Desktops on a native surface

Local

Your own machine, in the same list
